Description of intervention(s) / exposure
K-3505 P001 (PART I) is a study of K-3505 in healthy male and female participants. This will be the first administration of K-3505 to humans.
This is a single rising dose study composed of 2 sequential panels of 8 subjects each (Panels A and B), each having Screening (up to 28 days prior to first dose of study drug), Treatment, and Follow-Up (approximately 14 days after their last dose of study medication) periods. The Treatment period will include up to 4 dosing periods per panel.
All periods for both panels will involve a single administration of K-3505 or placebo except for the final dosing period for Panel B. In the final panel tested, anticipated to be Panel B, Period 4, subjects will receive the same dose of K-3505 (or placebo) on 2 consecutive days. The dose of K-3505 used in this period will be within a range that was well tolerated during the dose escalation. Dosing is double blind meaning that neither the study participants nor the unit staff will know whether a participant is receiving K-3505 or placebo in a given treatment period.
Subjects will participate in either Panel A or Panel B and be randomized to a treatment sequence within that panel. This will result in subjects being assigned to K-3505 or placebo in a 3:1 ratio in each dosing period. All subjects will be randomized to receive placebo in 1 of the 4 dosing periods. For each panel, there will be at least 4 days between each dosing period.
Planned doses of K-3505 are noted below. All doses of K-3505 and placebo will be administered by intravenous (i.v.) infusion over approximately 2 minutes. All doses of K-3505 and placebo will be admiistered by nursing staff.
Panel A
• Period 1: 3 micrograms K-3505 or placebo
• Period 2: 10 micrograms K-3505 or placebo
• Period 3: 30 micrograms K-3505 or placebo
• Period 4: 90 micrograms K-3505 or placebo
Panel B
• Period 1: 250 micrograms K-3505 or placebo
• Period 2: 750 micrograms K-3505 or placebo
• Period 3: 2000 micrograms K-3505 or placebo
• Period 4: Dosing of K-3505 or placebo on 2 consecutive days. The dose of K-3505 will be the same on both days and will be within the range of doses that was well tolerated in earlier periods.
In all dosing periods, subjects will be admitted into the study unit on the day prior to K-3505 or placebo administration (Day -1). They will fast a minimum of 8 hours (overnight fast) prior to K-3505 or placebo administration and will remain domiciled for at least 24 hours after K-3505 or placebo administration for safety monitoring and to assess pupillary responses. In the two-day dosing period (planned for Panel B Period 4), subjects will also fast overnight from Day 1 to Day 2 and will be discharged after the completion of the Day 2 24-h assessments.

•The proportion of participants who experience 1 or more treatment-emergent adverse events (TEAEs).
•The proportion of participants who discontinue study medication due to a TEAE.
AEs spontaneously reported by the patient/subject and/or in response to an open question from the study personnel or revealed by observation will be recorded during the study at the investigational site. AE terms will be reported in standard, current medical terminology and coded using the latest version of the Medical Dictionary for Regulatory Activities (MedDRA). Additional information recorded with an AE will include the following, as determined by the study investigator: start/end dates and times, severity/intensity (graded as mild/moderate /severe according to standard definitions), causality (relationship to study drug), seriousness and action taken with study drug (including whether study drug is discontinued due to the TEAE).

TEAs are AEs that start or worsen during or after the first dose of study medication.
For Panel A, TEAEs will be assessed in Period 1 on Day 1 (after dosing) and Day 2, in Periods 2-4 on Day -1, Day 1 and Day 2, and at the post-study visit 14 days after the final dose.
For Panel B, TEAEs will be assessed in Period 1 on Day 1 (after dosing) and Day 2, in Periods 2 and 3 on Day -1, Day 1 and Day 2, in Period 4 on Day -1, and Days 1, 2, and 3, and at the post-study visit 14 days after the final dose.
For any subjects from Panel A or B who discontinue study medication early, TEAEs will also be assessed at the early termination (ET) visit.
Discontinuation of study medication for a TEAE may occur between start of dosing in Period 1 and completion of dosing in Period 4.

a Abstinence can be used as the sole method of contraception if it is in line with the subject’s preferred and usual lifestyle and if considered acceptable by local regulatory agencies and ethics committees. Periodic abstinence (e.g., calendar, ovulation, sympto-thermal, post-ovulation methods, etc.) and withdrawal are not acceptable methods of contraception.
